           Summary: Marvell 88E1145 phy configured incorrectly in fiber
                    mode
           Product: Drivers
           Version: 2.5
    Kernel Version: Linux-2.6.39-rc1-00191
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Network
        AssignedTo: drivers_network at kernel-bugs.osdl.org
        ReportedBy: oakad at yahoo.com
        Regression: No


On my board, Marvell 88E1145 phy is attached to Freescale gianfar controller.
Backplane connection is detected by u-boot as 1000/Full fiber mode.

The network works perfectly in u-boot (dhcp, tftp of large files, ntp). Upon
booting, kernel detects the link as 100/Full and no data can be exchanged over
the interface.

As a quick fix, I tried setting .read_settings method of the 1145 driver to
marvell_read_status (instead of genphy_read_status). Now the link is correctly
detected as 1000/Full, but the data still can not be exchanged.

I assume, there's a configuration bit missing on the kernel side, as there are
no such problems in u-boot.
